Abstract:

The present study intends to investigate micronutrient content of six commonly consumed greens namely Amaranthus spinosus, Chenopodium album, Spinaciaoleracea, Phyllanthus amarus, Talinum triangulare and Ludwigia adscendens after dehydration by using four different drying methods, i.e. sun drying, shade drying, cabinet dryer drying and microwave oven drying. Among the nutritional parameters, total mineral content, iron, calcium, potassium, phosphorous and ascorbic acid content was found highest in cabinet dryer dried samples, followed by microwave dried samples. Iron content was highest in dehydrated Amaranthus spinosus (86.80 mg/100g) followed by Phyllanthus amarus (32.50 mg/100g), Talinum triangulare (28.20 mg/100g) and Chenopodium album (25.30 mg/100g). Calcium content was found highest in dehydrated Amaranthus spinosus (2920.38 mg/100g) followed by Talinum triangulare (1206.67mg/100g) and Chenopodium album (1142.50 mg/100g). The phosphorous content was highest in Talinum triangulare (546.56 mg/100g) and Spinacia oleracea contained highest potassium content (2526.30 mg/100g) in cabinet dried samples. Microwave oven dried Talinum triangulare contained highest amount of ascorbic acid (13.96 mg/100g). Thus it can be concluded that the mineral content of all of the selected greens became concentrated after dehydration. These dehydrated leaves have good rehydration capacity for incorporation into various products to reduce micronutrient deficiency.
